So I just downloaded the latest DATFiles, and have been using them to audit my collection. All well and good, until I got to the Game Boy ROMs. For some reason, there are only 84 entries in the Games DATFile for the Game Boy, despite Wikipedia claiming over 800 games for the system. Link's Awakening, Super Mario Land, and Tetris are nowhere to be found, but "The Incredible Crash Dummies", "Waterworld", and "Zool" are all there. Also, the file extension for all of the ROMs is .bin, not .gb like basically all Game Boy ROMs these days.
